Abstract
In this article we report an experimental investigation of the far-infrared properties of several nonlinear crystals, LiNbO3, LiTaO3, ZnTe and CdTe. U sing Terahertz Time-Domain Spectroscopy (THz-TDS) we have measured the comp lex frequency response, i.e. both index of refraction and absorption up to 3 THz (100 cm(-1)) for the electro-optic crystals at room temperature. The single Lorentzian oscillator model is used to describe the aquired data. Ad ditional resonance features are observed, especially in the II-VI compounds .
